Answer:$6.13.
Step-by-step explanation: Cost per pound = $1.29
Weight of the watermelon = 4.75 pounds
Cost of the watermelon = (Cost per pound) x (Weight of the watermelon)
Cost of the watermelon = $1.29 x 4.75
Now, calculate the cost:
Cost of the watermelon = $6.1275
Now, round the cost to the nearest hundredth:
Cost of the watermelon ≈ $6.13
So, the cost of the watermelon Kelly buys is approximately $6.13.
